MM. This invention relate-s to carving machines particularly adapted forusein carving smoking pipes, the object of the invention being to provide a simple, eiiicient, inexpensive and "5 easily operated machine for rapidly carving the bowls and stems oi smokin 3i yes there by to glve them a rough or rustic appearance,

f5 stem carved on. this machine.

Similar characters of reference :indicate correspondlng parts 111 the several views.

, provement and mode of operation thereof, I

desire to have it understood that the invention is not limited to the details of construction and arrangement of parts which are i l:

lustrated in the accompanying drawings,

since the invention is capable of other embodiments, andvthat the phraseology which I employ is for the purposeof description and not of limitation.

The machine in its preferred form thereof comprises a base or bed-plate 2 having a suitable opening 3 therein for attachment to the work bench when desired. Supported by this bed-plate is a series of rotary conver ing spindles 4. which carry at their ends suit able carving tools 5 each shown in the form of a U-shaped tool. For supporting these rotary spindles, the bed-plate is provided at opposite ends with twosets of upright posts 6 and 7 the posts 6 at the rear. or driving end. of the bed being spaced a greater distance apart thanthe posts at the working ends of the spindles. I j

In the form shown the posts 6 consisting of three posts, are clampedby suitable nuts ,8 to the bed plate and for this purpose the plate is provided with a pair of elongated slots 9 through which the reduced ends 10 of the two outer posts extendwhereby the posts may not only be clamped to the bed plate, but may be adjustedtoward and from the center post which is likewise clamped to 1928. Serial No; 292,368. r a c the bed-plate, no adjustment thereof being necessary in viewot the factthat the outer posts can beadjusted toward and from the center: post. At the working end of the ma chine each of the set of three posts 7 is provided with reduced ends 11 extending through the bed-plate and secured in position by clamping bolts 12 projecting into the end of theplate. ,Bymeans otthese clamping bolts each of" the posts. 7 can. be raised or lowered whereby one orniore of the spindlesumaylhe raised or lowered so thatall of the spindles will. be in the same horizonalfplane. Thus, it will be understood that byadjusting one set ofposts, the spindlesmay beraised and lowered and by adjusting the outer posts of j the other set the spindleslnay be adjusted lat Before explaining in detail the present imj iff -j ouireo STATES PATENTQOFFICE ;1

erally toward and from the intermediate spindle. As this last set of posts is spaced further apart than the other set, therotary spindles converge toward the working ends thereof. i

By means :of the lateral adjustment carving ends of the spindles-can beadjusted to vary thesize or relative position'ot the carvings-of the pipe for either finerjorlarger carving, as desired. That is to say, the lateraladjustment enables the cutters to be brought closer together or spaced farther apart, according to the work that is to be When they are closertogether, the.

done. carving devlces do smoother or better work.

The vertical adjustment is to insure-that the carving devices will be in the same horizontal plane so that they will-all do preciseiy the same work, for onecarving devicebelow the other will not do the properwork. The" vertical adjustment, however, is very, slight and.

of three holes in thepipebowl; whereas, by

converging them, insteadv of makingholes, they operate to give the rustic effect on the pipe. By providingxthecutters with; two

prongs, sixcutting edges are thus. obtained, and by the formation of the two prongs, the resultis the cutting of the wood and not the If these, cutters were spaced apart boring thereof; whereas, if they only had one prong, the result would simply be the making of a hole, which would not look like carving. The cutters are run in opposite directions so as to maintain the pipe bowl steady in the hands of the operator, for if they were all run in one direction, the pipe bowl would be thrown out of the hands of the operator during the operation of the cutters.

Each of the spindles is provided with a grooved pulley 13, and a suitable belt 14, motor or otherwise driven, extends under the outer pulleys and over the intermediate pulley whereby the outer spindles are rotated right hand and the intermediate pulley left hand with a corresponding movement of the tools.

Each of the posts is provided at the top thereof with an opening 15 for the passage of oil to suitably lubricate the spindles.

In the operation of the machine the operator holds the pipe bowl or stem, as the case may be, in position against the working ends of the spindles whereupon the pipe is carved by the rotary spindles in the manner described to give a rustic or rough finish.

It is to be understood that by describing in detail herein any particular form, structure or arrangement, it is not intended to limit the invention beyond the terms of the several claims or the requirements of the prior art.

Having thus explained the nature of my said invention and described a way of constructing and using the same, although without attempting to set forth all of the forms in which it may be made, or all of the modes of its use, I claim:

1. In a machine for carving smoking'pipes, the combination of a supporting bed, a series of horizontally-located, converging, rotary spindles carried thereby and provided with carving cutters for simultaneously rustically carving smoking pipes to give them a rustic appearance, and means for rotating some of the spindles in one direction and the remainder thereof in the opposite direction.

2. In a machine for carving smoking pipes, the combination of a supporting bed, a series of horizontally-located, converging rotary spindles carried thereby and provided with carving cutters for simultaneously rustically carving smoking pipes to give them a rustic appearance, and means for rotating some of the spindles in one direction and the remainder thereof in the opposite direction, each of said spindles having a cutter provided with a plurality of prongs.

3. In a machine for carving smoking pipes, the combination of a supporting bed, a series of -horizontally-located, converging, rotary spindles carried thereby and provided with carving cutters for simultaneously rustically carving smoking pipes to give them a rustic appearance, and means for rotating some of the spindles in one direction and the remainder thereof in the opposite direction, each of said spindles having a U-shaped cutter.

4. In a machine for carving smoking pipes, the combination of a supporting bed, a series of horizontally-located, converging, rotary spindles carried thereby and provided with carving cutters for simultaneously rustically carving smoking pipes to'give them a rustic appearance, means for rotating some of the spindles in one direction and the remainder thereof in the opposite direction, and means for adjusting some of the spindles laterally.
